I don't think we will replace him and I wonder if we might see a change of formation soon. I don't see Leonard, Holmes and Evans being sat on the bench for long and Fleck and Duffy aren't getting dropped any time soon, so switching to 4 at the back would make room for an additional midfielder.
4-2-3-1 [which was Wilder's preferred formation at Northampton] or even a 4-2-2-2 could work. The 3-5-2 served us brilliantly for a long time but everything runs its course and goes a bit stale eventually. Whether it's down to losing Coutts, or that teams have now figured out the wingback/CB overlap system, we just seem to have lost a bit of something. A change could give us a lift and the thought of Duffy, Holmes and Brooks marauding behind the CF, with Fleck, Evans, Lunny and Lenny to choose from in CM is a very exciting prospect.
